In mid-October of 2017, Bring Me the Horizon vocalist Oli Sykes and keyboardist Jordan Fish scaled Mount Kilimanjaro, a dormant volcano in Tanzania and the highest mountain in Africa at 19,340 feet. The U.K. rockers, who are about to drop their new album Amo, did this to raise money for the Pediatric Intensive Care Unit at Southampton Hospital, which helped Fish's then–4-year-old son, Eliot, recover from a brain hemorrhage. Fish reports that his son is doing very well now and they were able to donate over £70,000. While the BMTH members' climb was serious in nature, it doesn't mean the guys didn't have fun on the trek, as evidenced by their posts on Instagram. And they bonded in other ways, too: When Revolver recently asked about the most memorable moment from the experience, Sykes quickly replied with a story about needing to go No. 2 at the top, where there was a distinct lack of amenities. "But just to show you how good of a friend I am," proclaimed Fish, "I gave him my hat to wipe his ass." Watch the two hilariously recount the legend of how Fish's soiled hat "to this day, remains at the top of Mount Kilimanjaro."
